a study to evaluate the effects of azilsartan on coronary artery plaque in essential hypertensive patients with stable angina and dyslipidemia.

Conditions: Essential Hypertension With Stable Angina and Dyslipidemia

Summary: the purpose of this study is to evaluate the effects of oral azilsartan once daily for 32 weeks on coronary artery plaque in essential hypertensive patients with stable angina and dyslipidemia.

the open-label design without a control group was selected because this clinical study primarily aims to explore the effects of azilsartan on coronary artery plaques. this study targeting patients with coronary artery plaque has been designed to enroll hypertensive patients with dyslipidemia. also in light of the invasive nature of the major assessment procedures (i.e., ib-ivus, oct), this study will only enroll patients with stable angina planned to undergo percutaneous coronary intervention with stent placement, among patients with coronary artery plaque. the starting dose of azilsartan has been set to 20 mg on the basis of the usual clinical dose of the drug in patients with essential hypertension, and dose increase of azilsartan will be permitted only when the target blood pressure has not been achieved. the duration of treatment has been set to 32 weeks in line with clinical practice, in which coronary angiography is typically performed after a 32-week follow-up period following pci with stent placement.

Eligibility criteria:
inclusion criteria: 1. patients with essential hypertension with office blood pressure before the start of study treatment (week 0) meeting the following criteria who are appropriate for azilsartan therapy in the opinion of the principal investigator or investigator * patients aged ≥ 75 years at the time of informed consent: sitting systolic blood pressure ≥ 150 mmhg or sitting diastolic blood pressure ≥ 90 mmhg * patients aged \< 75 years at the time of informed consent who concurrently have type 2 diabetes mellitus: sitting systolic blood pressure ≥ 130 mmhg or sitting diastolic blood pressure ≥ 80 mmhg * patients aged \< 75 years at the time of informed consent who concurrently have chronic kidney disease (ckd) with proteinuria: sitting systolic blood pressure ≥ 130 mmhg or sitting diastolic blood pressure ≥ 80 mmhg * patients meeting none of the above: sitting systolic blood pressure ≥ 140 mmhg or sitting diastolic blood pressure ≥ 90 mmhg 2. patients with stable angina with a coronary stenosis confirmed by coronary angiography who are planned to undergo percutaneous coronary intervention with stent placement (any type of stent) 3. patients with findings of integrated backscatter intravascular ultrasound (ib-ivus) to be performed before the start of study treatment (week 0) showing plaque at (≥ 5 mm in length) ≥ 5 mm proximal to the proximal end of the inserted stent in the coronary artery 4. patients with dyslipidemia meeting both of the following criteria: * patients treated with one hmg-coa reductase inhibitor with no change in the dosage for at least 12 weeks before informed consent * patients with an ldl-c level of \< 100 mg/dl as shown by a laboratory test performed within 4 weeks before informed consent 5. men or women aged 20 or older at the time of informed consent 6. patients capable of making outpatient study visits throughout the observation period 7. patients who, in the opinion of the principal investigator or investigator, are capable of understanding the contents of the clinical study and complying with the study requirements 8. patients capable of providing written consent in person before any study procedures exclusion criteria: 1. patients with secondary hypertension or malignant hypertension 2. patients who took any renin-angiotensin system inhibitor within 12 weeks before informed consent 3. patients who previously underwent coronary artery bypass grafting 4. patients with type 1 diabetes mellitus 5. patients with insulin therapy 6. patients with an hba1c level (national glycohemoglobin standardization program \[ngsp\] value) of ≥ 7.0% as shown by a laboratory test performed within 4 weeks before informed consent 7. patients with the plaque unevaluable because of severe calcification of the coronary artery shown by ib-ivus to be performed before the start of study treatment (week 0) 8. patients with a change to their antidyslipidemic medication (including a change to the dosage) within 12 weeks before informed consent 9. patients with clinically evident renal disorder (defined as estimated glomerular filtration rate \< 30 ml/min/1.73m2) 10. patients with severe liver disorder 11. patients with hyperkalemia (defined as serum potassium ≥ 5.5 meq/l) 12. patients with a history of hypersensitivity or allergy to azilsartan 13. patients participating in any other clinical study 14. pregnant women, women with possible pregnancy, or breastfeeding women 15. other patients who are inappropriate for participation in this study in the opinion of the principal investigator or investigator
